HAIR TODAY, GONE TOMORROW: James Lipton shares his beard on a PSA about texting.

Talk about a face-off — or in this case, a “beard-off.”

“Inside the Actors Studio” host James Lipton has shot a series of public service announcements in which he removes his famous beard (via clever digital graphics)– and places it on kids who are about to send nasty and/or racy text messages.

It’s all a part of phone giant LG’s “Give it a Ponder” campaign, aimed at getting kids and teens to think twice about what they’re texting to friends and frenemies.

In one spot (pictured above), a young teen, “Vicky,” is pondering texting some malicious gossip about her friend, Jessica — so she can steal Jessica’s “oven-mitt-hot” boyfriend, Luke, “and pry them apart.”

But after “giving it a ponder” — by stroking the beard that Lipton removes from his face and places on hers — Vicky thinks about the ramifications of such a text and decides to nix the idea.

In another spot, a guy (who’s brushing his teeth) thinks twice before spreading malicious gossip about the girl who just broke up with him — using his Lipton “beard” to “ponder” the situation.

The ads were created for LG by Young & Rubicam and were posted all over the Internet yesterday, including ad-freak.com.
